Frequently Asked Questions for Importers & Contractors
1. Can we combine galvanized wire, tie wire, and nails in one container?
Yes! This is one of our key competitive advantages. We provide flexible 1x20GP mixed container consolidation (e.g., 10 tons GI wire + 8 tons black annealed tie wire + 7 tons common nails) to maximize space and lower your freight cost.
2. What is the difference between Hot-Dip Galvanized Wire and Electro-Galvanized Wire?
Electro-galvanized wire has a bright, smooth finish with 10–25g/m² zinc, ideal for indoor binding and wire mesh. Hot-dip galvanized wire carries 40–300g/m² heavy zinc, offering 10+ years of rust protection for outdoor fencing, gabions, and harsh coastal environments.
3. What packaging options are available for black annealed tie wire?
We supply 1kg–5kg small coils for hand rebar tying, 25kg–50kg standard coils, and pre-cut straight tie wires / U-type looped wires packed in cartons and pallets.
4. What are your standard payment terms?
Standard terms are 30% T/T deposit and 70% balance against B/L copy, or 100% confirmed Irrevocable L/C at sight.
5. Do you provide MTC and tensile test reports with each batch?
Yes. Every shipment includes an EN 10204 3.1 Mill Test Certificate detailing chemical composition, wire diameter tolerance, elongation percentage, and zinc weight verification.
